Press-in contact

Abstract

A press-in contact to be pressed into a throughplated hole of a printed circuit board includes a contact spring or a contact pin, a middle shaft portion connected to the contact spring or pin, and a connecting pin forming an extension of the middle shaft portion. The contact spring or the contact pin has in the transition area to the shaft portion a press-in shoulder. The shaft portion is provided with a slot-shaped opening whose sides are formed by legs. Each end of the slot-shaped opening has an approximately parabolic configuration. The slot-shaped opening is conically shaped and the end of the slot-shaped opening facing the contact spring or the contact pin extends into the area of the contact spring or the contact pin.

We claim: 
     
       1. A press-in contact adapted to be pressed into a throughplated hole of a printed circuit board, the press-in contact comprising a contact member, a middle shaft portion connected to the contact member, and a connecting pin forming an extension of the middle shaft portion, wherein the contact member has in a transition area thereof toward the middle shaft portion a press-in shoulder, wherein the middle shaft portion comprises legs defining a slot-shaped opening, wherein the slot-shaped opening has ends, the ends having an approximately parabolic configuration, wherein the end of the slot-shaped opening facing the contact member extends into the contact member, wherein the end of the slot-shaped opening facing the connecting pin is torpedo-shaped, and wherein the end of the slot-shaped opening facing the contact member has a greater width than the end facing the connecting pin, and wherein the slot-shaped opening has a reduced width portion between the two ends. 
     
     
       2. The press-in contact according to claim 1, wherein the contact member is a contact spring. 
     
     
       3. The press-in contact according to claim 1, wherein the legs defining the slot-shaped opening comprise pressed-on elements at outer sides thereof. 
     
     
       4. The press-in contact according to claim 3, wherein each pressed-on element extends from the press-in shoulder to the connecting pin.
